k. This application has been accepted for filing and is now ready for environmental analysis.

l. The existing Mattaceunk Hydroelectric Project consists of: (1) A 1,060-foot-long, 45-foot-high dam (Weldon Dam) with a crest elevation of 236.0 feet (USGS datum), and includes: (i) A 110-foot-long earthen embankment extending to the left abutment; (ii) a combined intake and powerhouse structure; (iii) an upstream fish ladder; (iv) a 10-foot-wide log sluice structure, controlled by an 8-foot-high vertical slide gate; (v) a 90-foot-long, 19-foot-high gated spillway with a single roller gate; (vi) a 657.5-foot-long, 70-foot high concrete gravity overflow spillway with 4-foot-high flashboards to create a maximum flashboard crest elevation of 240.0 feet; and (vii) a retaining wall at the right abutment; (2) a 1,664-acre reservoir with a total storage capacity of 20,981 acre-feet at a normal pool elevation of 240.00 feet (USGS datum); (3) a 142-foot-long, 99-foot-wide powerhouse (Weldon Station) integral to the dam containing two Kaplan turbines rated at 5,479 kilowatt (kW) and two fixed-blade propeller turbines rated at 5,489 kW, each driving a 6,000 kilovolt-ampere (kVA), 4,800 kW vertical synchronous generator for an authorized installed capacity of 19.2 megawatts (MW); (4) a downstream fishway; (5) an outdoor substation adjacent to the powerhouse; (6) a 9-mile-long, 34.5-kilovolt (kV) transmission line within a 120-foot-wide right of way; and (7) appurtenant facilities. The project generates about 123,332 megawatt-hours (MWh) annually.

The Mattaceunk Project is operated with minimal fluctuations of the reservoir surface elevation. Flexibility on reservoir elevations is required to provide for safe installation of the project's flashboards and to allow an adequate margin for wave action, debris loads, or sudden pool increases that might cause flashboard failure. The existing license requires a reservoir surface elevation no lower than 1.0 foot below the dam crest elevation of 236.0 feet when the 4-foot-high flashboards are not in use, and no lower than 2.0 feet below the top of flashboard elevation of 240.0 feet when the 4-foot-high flashboards are in use. The existing license also requires a year-round continuous minimum flow of 1,674 cubic feet per second (cfs) or inflow, whichever is less, and a daily average minimum flow of 2,392 cfs from July 1 through September 30 and 2,000 cfs from October 1 through June 30, unless inflow is less than the stated daily average minimum flows (in which case outflow from the project must equal the inflow to the project). Great Lakes Hydro proposes to: (1) Install a seasonal upstream eel ramp; (2) install an upstream passage structure for American shad, alewife, and blueback herring; (3) install trashracks having 1-inch clear spacing to the full depth of the turbine intakes during the fish passage season; and (4) improve the recreation facility at the downstream angler access area.
